Hi All. I just have a unit installed. Do I really need to have a discharge pipe installed? The tank is filled with water and air has been purged. The TP relief valve is installed. If pressure gets to high I assume I would see leak from the valve. It’s at a small business and flooring is tile so a small amount of water on the floor is not a problem and the unit would be turned off when we’re not there. The installation would require additional piping across a room. Also the instructions say to relieve the valve once a month but at the risk of messing up the valve. So is that necessary?
